Singer Shakira has cancelled the first show of her upcoming El Dorado world tour due to vocal strain. The 40-year-old was supposed to kick off her roadshow on Wednesday in Germany, reports aceshowbiz.com. “During these last few days of rehearsals, I have unfortunately strained my vocal cords and as a result my doctors have ordered me to go on vocal rest to avoid any greater damage that could keep me from performing.”
